I bought this software yesterday and it does not work. It will not even play a standard DVD.
The rating of this software is not so high and its activity it's low among other video players. Try to perform an update if you can or switch to a capable video player. VideoLAN is a video player capable more than enough to play DVDs.
Try Mac free Mac Media Player here, works great on DVD, as well as other media formats. http://goo.gl/NWqQMc
